PIVOT MOUNTING.

Application filed October 19, 1921. Serial No. 508,?08.-- v

To all "whom it may concern: Be it known that I, HALVO'R O. HEM, acitizen of the United States, residing at T0- ledo, in the county ofLucas and State of Ohio, have invented certain new and usefulImprovements in Pivot Mountings, of whlch the following is aspecification.

This invention relates to pivot mountings, and particularly to means forsecuring knife edge pivots to scale levers. One of its'principal objectsis the provision of reliable and inexpensive means for securing pivotsto scale levers.

Another object is the provision of a mounting which may be fixed inplace upon the scale lever by means of simple tools,

Still another object is the provision of a, pivot mounting which may besecuredto the lever in any desired position and which requires nopreparation of the lever to receive it other than the boring of acylindrical hole.

Other objects and advantages willbe apparent from the followingdescr1ption, 1n which reference is had to the accompanying drawingsillustrating a preferred embodiment of my invention and wherein similarreference numerals designate similar parts throughout the several views.

In the drawings 1 Figure 1 is a fragmentary elevation of a lever havingpivots secured thereto by means of my improved device;

Figure 2 is an enlarged sectional vlew taken substantially on the line2-2 of Fig- I ure 1, the fulcrum stand being omitted; and Figure 3 is anenlarged perspective view of the pivot mounting disassembled and 'detached from the lever.

r Referring to the drawings in detail, the lever 1 may be of any desiredtype. 'My invention is, however, particularly applicable to levers whichmust be made especially for particular installations When scales areinstalled in factories and other industrial establishments it is oftendesirable to place the commodity-receivers and indicating mechanism insuch relative positions that special extension levers are required tocon-' inventiomhowever, the pivots may be easily located in any desiredposition on suitable blank levers or upon bars which may be easilycut'to the desired length from regular commercial stock.

In mounting the pivots, suitable cylindrical apertures 2 are bored inthe lever, these apertures being of the proper size to snugly receivethe shank portions 3 ofthe pivot retainer, the body of which, as isclearly shown in Figure 3, is shaped substantially like a cap screw,having a poly-sided head 4 atoneiend and threads 5 at its other end.Extending axially intoeach end of the pivot retainer body is a taperedhole 6 and driven tightly into the tapered holes 6 are the similarly.tapered shanks 7 of knife edge pivots 8, the edges of which areinexaotaline 1 To secure the pivot retainer to the lever it is onlynecessary to insert the shank 3 in the opening and clamp the device inplace by means of the nut 10, care being, of course, taken to seethatthe knife edge pivots are properly located when the device isfinally clamped in place. I

While it will be apparent that the illustrated embodiment of myinvention herein disclosed is well calculated to adequately fulfill theobjects primarily stated, it is to be understood that the invention issusceptible to variation, modification and change within the spirit andscope of the subjoined claims.

'Having described my invention, I claim:

1. In a device of the class desoribed,.'in

combination, apivot retainer having a, portion adapted to be passedthrough a lever, a shoulder at one end of said portion said shoulderadapted to engage one of the sides I of the lever, means adapted toengage the other side of said lever for clamplng-the pivot retainer inposition, and a knife edge pivot separably secured to said pivotretainer. v
